SHlNGLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 561,279, dated June 2, 1896.

Application filed August 2, 1889. Serial No. 319,528- (No model.)

To all whom it may concern.-

Be it known that I, WILLIE; J. PERKINS, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Shingle-Sawing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to shingle-machines in which a number of shingle blocks or bolts are carried by a continuously-movin g carriage to a saw or plurality of saws, and a shingle is sawed from each block as it passes the saw.

The object of the present invention is to improve the construction of the block clamping and supporting devices; also to place the operating parts of the machine well under the control of the operator who by the adjustment of suitable stops or catches with reference to any of the bolt carriages or carriers can then depend on the machine to automatically complete the function for which said catch or stop was intended, as to throw out the spalt, feed in a new block or bolt, or perform other operations generally performed by hand.

In general the object of the invention is to produce a machine which shall be nearly selfoperating or automatic when driven by a suitable motor.

Figure 1 is a partial plan of the improved shingle-machine, the blocking-shelf and many of the working parts being omitted. Fig. 2 is a side elevation, some parts being omitted. Fig. 3 is a detail section through center of one carriage, showing automatic spalter and other mechanism. Fig. 4 is a detail elevation showing a portion of the rotating carriage and tilt-operating arms. Fig. 4 is a perspective of the leverM and connections. Fig. 5 is a broken top plan of the actuating-arm and trips. Fig. 6 is a broken elevation showing end of actuating arm. Fig. 7 is a plan of stationary handles for operating the trips. Fig. 8 is an outer end elevation of same. Fig. 9 is apartial section of the rotary carriage, showing in elevation the handles and actuating-arm. Fig. 9 is a detail elevation of handles, showing one handle depressed and another elevated. Fig. 10 is a perspective View of the end of the doggingrod and catch for holding the same open.

Fig. 11 is an enlarged detail of part of Fig. 1, showing the operating connections of the bolt-supporting shelf. Fig. 12 is an enlarged broken detail plan, showing automatic bolt or block feeding devices. Fig. 13 is an elevation of the automatic bolt or block feeding device. Fig. 14 is a diagrammaticrepresentation of the shelf-supporting and disengaging mechanism hereinafter referred to. Fig. 15 is a diagrammatic representation of the devices for raising the block or bolt follower.

The general arrangement of the rotary carriage, saws, and tilt-table is preferably such as is shown in my Patent No. 380,346, of April 3, 1888. It will be understood, however, that many of the improvements herein set forth may be used in other machines than the patented'machine referred to.

A indicates the shingle-bolt carriagein this case a rotary carriage-having ten (more or less) receptacles a for shingle-bolts. This carriage is preferably supported by spider B from the central shaft 0, as has been done before in machines of this class, but may be otherwise made.

Each bolt receptacle or carrier at has a movable bolt-dog b and a stationary dog 0. The movable dogs I) slide in ways parallel with the rear or pushing faces of the carriage or bolt-receptacles. The dog is drawn inward by a sliding arm at, which rides in guides on the carriage A and is actuated by a spring G, which surrounds the arm and has a bearing on the frame and also on a nut e or boss on the bent arm d. The inner ends of the sliding arms d have bearing rolls or surfaces 3, which in a general Way resemble those shown in my Patent No. 380,3 of April 3, 1888.

The rolls 3 engage cams or inclined surfaces 4, which are fixed relatively to the rotating carriage in such position as to bear against rolls 3 and press out the dogs b at the proper time in the rotation of the carriage.

The inner end of each arm at has a bracket 2, which bracket carries a roll 5, Fig. 10. The rolls 5 ride against inclined surfaces .6, carried by the ring v7 and take the strain of the parts when the rolls 3 encounter inclines 4 or 4. The ring '7 is attached to the central shaft 0, which supports the rotating carriage.

Returning now to Fig. 10, the numeral 9 shows a hook or projection on the arm (1 or ICU bracket 2. A hook 10 is borne by a suitable pivot 8, supported on the carriage A in proxilnity to the inner end of the arm d. The hook 10 has a downwardly-projecting lug 12, which is in position to engage an incline 1 3 on the frame at a suitable point in the rotation of the carriage. As the lug 12 rides up 111- cline 13 when carried along by the carriage movement it lifts the hook 10 out of engagement with projection 9, thus leaving arm (Z free to move under the influence of its spring; but when lug 12 is not in engagement with the incline 13 the hook 10 falls inside the projeetion 9, as roller 3 is forced outward by incline 4. Hook 10 thus holds the arm d pressed outward against the tension of its spring, relieving roller 3 from the friction which would arise if the incline l was continued for a long distance in an arc of the circle described by the rotation of the carriage, as has been done heretofore. The bearing or incline 4 is located on the frame in such position as to undog the bolt as it approaches the tilt-table.

The incline at is carried by alever 14, and may be integral with said lever. (See Figs. 2 and 1.) Lever 11 is pivoted to a support 011 the frame 15, and the outer end of the lever has contact with the cam 16, carried by arm 17 on the upright rock-shaft 1S, suitably supported in the frame or support of the machine. The upper end of rock-shaft 1S bears an arm 19, which is engaged by the actuating-arln 20 on the carriage at proper intervals and under proper conditions. A lever 21 is pivoted to the inner end of lever 14.- and suitably supported 011 the frame. The upturned end of this bell-crank lever 21 bears an incline 22. \Vhen the incline or abutment a is raised into position to operate the dog, this incline 22 will be depressed, and vice versa. The arm 14 also carries an inclined abutment and an arc piece 24 nearly concentric with the carriage. Each bolt-compartment of the carriage has a lever 2 7 (elearl y shown in Figs. 3 and 11) pivoted to the carriage, with a bent arm extending over the shingle-bolt. The pivoted end of said arm or lever 27 has a segment-gear 27 concentric with its pivot, and this gear engages with a mutilated gear 26, pivoted or j ourn aled to the carriage and having a tooth or projection 25, which engages the are 24 when the latter is elevated into engaging position in the act of ejecting the spalt from the machine and raises arm 27 to allow a new shin gle-bolt to be placed in the carriage. A bell-crank lever 28, Figs. 3 and 11, is pivoted to the carriage at each bolt-compartmcnt. One arm of this lever 28 is pivoted to a rod 29, which extends outward] y to the rim of the carriage adjacent to one of the trips in the actuating-arm 20,whieh will be described hereinafter. The front end of arm 27 extends above and across the inner end or face of the bolt-compartment, and when this arm 27 is depressed it bears on the free arm of bell-crank 28, thus thrusting the rod 29 outwardly. This only happens when the arm 27 falls to its lowest position in following the bolt down while said bolt is being sawed into shingles.

It is desirable to remove the spalt when it is reduced in size to a certain thickness, and the arm 27 should descend far enough to rest on the thinnest spalt that it is safe to make on the machine, but not far enough to come in contact with the saw before actuating the spalt-expelling mechanism.

A block-supportin g shelf 30 is shown in Figs. 3, 11, and 14 as arranged under the fixed. dog at the inner end of the shin gle-bolt carrier. The shelf is supported by links 31, pivoted to the carriage and to the shelf. A hook, catch, or rest 32, also pivoted to the carriage, drops under a projection, 30, on said shelf whenever the shelf is lifted, so that this hook can engage therewith. The hook 323 has an incline 32 and a weighted arm 320, which. arm tends to throw it forward. -When the shelf is lifted into position to engage the hook, it first engages the incline 32" and swings the hook a little back, and, as shown, as the shelf passes the point of the hook the weighted arm causes the hook to swing forward and support the shelf. Vhen held up by the hook 32, the shelf is back under the bar of the carriage, as in dotted position, Fig. 11, and is then inoperative. The object of the shelf is to support one end of the shingle-bolt at certain times and prevent it from twisting in the binding-dogs. To cause the shelf to so operate, suitable meehanism is provided as .[:'ollows: There is a fixed bar on the frame. This bar is for a part of its length curved circumferentially of the machine and for a part of its length is inclined to such curve, extending toward the center, as shown in dotted lines, Figs. 1 and 11 and in Fig. 14.. \Vhen the incline 22 (connected, as heretofore described, to lever it) is in its normal or elevated position, it will be engaged by the counterbalancing-arm 320 of hook 32 during the carriage movement, and hook 32 will thus be disengaged from the shelf. Being thus freed the shelf drops down on the bar 331. A downward projection 301 on the shelf is thus carried outside of the inclined part of bar 33], and as the shelf moves along with the carriage the shelf is swung outward until the projection thereon reaches the CllCl'llflfOlOTltlZLl part of bar 331, when the shelf will move circumferentially, being supported at its outer edge by said bar. \Vhen so projected. and supported, the edge of the shelf extends under the inner end of the shin gle-bolt and will tend to prevent the twisting of said bolt in the dogs; but it is apparent that the shelf would be in the way of the saw if carried full y around the machine under the dogs, and would also interfere with the tilt of the block. Therefore the incline or abutment 33 is applied on the frame, and as the carriage moves forward some part of the shelf encounters said incline, and by said incline the shelf is pressed inward toward the center of the machine (the links permitting considerable freedom of move the dropping of the spalt, as hereinafter described.

It will thus be seen that the bolt is never supported on a fixed way or track beneath the bolt-compartment at that point in the rotation of the carriage where it is desired to expel it from the machine, but that at certain times the inner end of the bolt may be supported by the movable shelf 30 I have described, and this will occur whenever the shelf is in operative position and the bolt slips or tips in the binding-dogs and at no other time. The shelf is held back by the hook 32 for the purpose of permitting the dropping the spalt, as described.

Bolt-supporting ways may be used between the back of the saw and tilt-table excepting at the point where the bolt or spalt is to be expelled.

An actuating-arm 20, Fig. 5, is pivoted at 35 to the carriage A, opposite each bolt-compartment a. Each arm 20 carries three (more or less) sliding stops 37, 38, and 39, and each stop has a pin 40, 41, and 42, extending upward into position to engage the lever 36 and push said lever off the lug 101 when either slide is drawn outward.

All the slides move in slideways on the arm 20. Slide 37 is moved outward by rod '29, hereinbefore mentioned, which rod is pressed outward by the bell-crank lever 28 whenever the arm 27 shall have fallen far enough to move this lever 28 through the connections described. I

Arm 20 is shown in Fig. 9 as elevated at its outer end above the rim of the carriage and in Fig. 3 as resting on said rim. The bar 36 is pivoted to the arm 20 and extends across said arm, passing under a hook or bracket 102 on said arm and resting normally on the lug 101, being pressed in this direction by a spring 100, Fig. 5. When pulled off from this lug 101, the bar 36 permits arm 20 to fall down, as in Fig. 3.

Assuming arm 20 to be in its elevated position, Fig. 9, when rod 29 pushes the slide 37 outward, the slide is then in position to cause its downwardly-proj ectin g lug or abutment 52 to be caught by the incline 57, Fig. 1, which stands on the frame outside the rotary carriage. The ineline'57 thus acts to pull said slide still farther out. The pin 40, carried by slide 37, throws arm 36 off from lug or stud 101, permitting arm 20 to fall down onto the carriage-rim, as in Figs. 3 and 6.

When arm 20 is in its lowered position, the roller or abutment 34, carried by said arm, is in a plane to engage arm 19 on rock-shaft 18, thus operating lever 14, depressing the outer end of said lever, and raising the incline 4, so that the roll on the inner end of the dog-rod engages said incline 4 opening or disengaging the dog and dropping the bolt or spalt. At the same time the incline 22 is depressed, which leaves the shelf-holding hook 32 in engagement with the shelf 30 to hold the shelf from falling back under the spalt or bolt. The block or spalt being thus unsupported must fall. Arm 20 and its connections thus serve as a trip to actuate the movable piece 19 when said arm 20 is in its dropped or abnormal position. Movable piece 19 in turn actuates lever 14, through the rock-shaft 18 and arm 16, and this lever 14 moves the movable part 4 into position to open the dog and drop the spalt. This happens whenever the slide 37 is actuated, as above described, and as hereinafter explained the slide 37 is under control of the arm or handle 46,which is manipulated in one direction by the operator, or, as further explained, the arm 46 may be held by handle to operate on all the trips 37 of the carriage and work the dogs to drop all the spalts.

As hereinafter explained, all the arms 20 are returned to normal position at incline 106 on the other side of the machine from the operator.

The are 24, carried by lever 14, is in the path of travel of the projection or tooth 25 of the mutilated gear 26, and when this are 24 is thrown up by the movement of the lever 14 the projection 25 will engage said are and the engagement will cause the lifting of arm 27 to position to permit the insertion of another shingle-bolt in the carriage-compartment under said arm 27.

Each slide 37 38 39 (carried by arm 20) is provided with an upwardly-projecting inclined surface 43 44 45 near its outer end, the incline being at an angle to the path of movement of the slide in the carriage. They are also provided, respectively, with the downwardlyprojecting lugs 52, 53, and 54, the lower ends of these lugs being in different horizontal planes.

A standard 70, outside the carriage and suitably connected to the frame, supports an arm 71, which is about tangential to the carriage. This arm 71 has three handles 46, 47, and 48 pivoted thereto. The handles 46,47, and 48 have downwardly-projecting inclines 49, 50, and 51.

It will be observed that the inclines 49, 50, and 51 are not at the same distance from the center of the carriage and that the corresponding inclines 43 44 45 are in similar relative arrangement. Consequently the handles do not interfere with each other. \Vhen one of the handles, say 4:6, is pressed down by the operator, its incline 49 catches the incline 13 of slide 37 and draws out said slide as the carriage rotates.

Arms and 81, (luplicated on opposite sides of the machine, Figs. 1 and 2, and outside the rim of the carriage, are rigidly attached to rock-shafts 82 and 83,which are connected bya suitable gearing or links to move together in opposite directions. The arms 80 and 81 are in different planes, so that the roller or abutment 34, in different positions, may engage one or the other and by rocking the arm outwardly swing the rock-shafts S2 and S3. Shaft 82 has an arm Sl which works a pitman or connecting-rod 85, leading to the operating mechanism of the tilt-table. The pitman 85 connects with lever 86, fulcrumed on the upright standard of the frame. The other end of lever 80 comes between pushlugs 87 87 on bar 87. Bar 37 is connected to the joints of the toggle-links S8 89, one toggle being at each side of the standard. The toggle-links are pivoted at their upper ends to the rockers 9O 90, which in turn supports risers 91 91 at the sides of the tilt-table 90, in the general manner shown in my Patent No. 380,316, of April 3, 1388, and in application, Serial No. 308,150, filed April 21, 188$). Arm 20 when in. normal position acts on arm 80 and returns tilt-table to its normal inclination.

The general arrangen'ient of the saws, carriages, and tilt-tables is similar to that shown and described in said Patent No. 380,316. The automatic features resemble those described in said application.

The tilt-tables operate to drop one or the other end of the shingle-bolt, so that it may be below the level of the saw, as in my patent last referred to.

It will be understood that one of the handles, as 17, serves to draw out a slide, as 38, which slide serves to adjust the height of the outer end of the arm 20 to work one tilt-table, and another handle, as 48, may be similarly adjusted to operate its train of connect-ion to set the othertilt-table, while the arm 46 may be used to work the spalt-dropper instead of using the automatic spalt-dro 'iper hereinbefore described. Incline 55'! on arm 20 acts alike on the handles etti, t7, and 18, raising them to their normal position. Springs 131, fastened to handles ili, 4:7, and 4S, catch over suitable projections on standard 70 and retain said handles in normal position. Handle (50 is journaled in a boss on standard 70 and has an eccentric on the outer end of said journal adapted to raise spring (31 on the handle 11; off its locking-lug.

\Vhen it is desired to throw out the spalts from the several carriages, handle (30 is adjusted, thereby preventing handle -16 from being held up, and allowing it to work on all of the bolt-compartments, as heretofore described, as fast as they approach it.

55, Fig. 1, is an incline having its angle away from the carriage-wheel and being on a plane suitable to engage with depending lug 5-i on slide 3.), Fig. (i.

103 is an incline on the frame adapted to raise arm 20 to its normal position. Spring then acts on lever 36, drawing same over lug 101, thereby retaining arm 20 in elevated position. Incline 10+ on frame or saw-guard is adapted to engage with lug 54, pushing same inwardly into normal position. Incline 105 is adapted to engage with depending lug 53 and draw out slide 38 for the purpose of operating the second tilt. Incline 106 is adapted to elevate arm 20 into normal position at the other side of the machine, while incline 107 is adapted to engage with depending lug 5E3, replacing same in normal position. Incline 57 is adapted to engage with depending lug 52, drawing slide outwardly. Incline 108, Fig. 1 is adapted to elevate arm 20 into normal position, while incline 10$) acts on depending lug 52 and returns slide 37 into normal position.

The belts or blocks to be sawed into shingles are carried automatically to this machine by mechanism now about to be described.

Referring to Figs. 1, 12, and 13, the numeral 110 (see Fig. 13) indicates afeed-shaft, around which an endless belt 111 passes. The belt then passes over idlers 112 and 11.) to a driving-pulley of shaft 115, which shaft is suitably supported on the frame of the machine. The shaft 115 carries a gear 116, which meshes with a gear 232. This gear 232 carries a crank or wrist pin 11S. A slotted arm 272 is pivoted to the frame, as at 115), and the wrist-pin 11S enters the slot in this arm, causing the arm to rock on its pivot with the rotation of gear 232. The arm 272 has a pusher pivoted to its upper end, the end of said arm being supported by a spring 271. The toe of this pusher 120 passes through a slotor opcnin g in the supporting-platform 282, which platform is close along the side of the rotary carriage of the machine and a little above the top thereof. A perpendicular arm or stop 262 extends up through the slot in platform 282, near the carriage, and when elevated serves as an abutment to prevent the bolts from being pressed onto the carriage. This step is held up by a spring 201. A lever 121 is pivoted to the frame and also pivoted at one end to the stop 262. The free end of this lever 12]. extends over a cam or hearing-piece 2.1.2 on. the gear 232, and when the gear-wheel 232 rotates it lifts the free end of the lever and forces down the step 262. The beltwill move all the time, but will slip on its pulleys when the parts are locked, as will be described, or in place of this slipping friction movement I may substitute a positivemotion with a dwell. A stop or catch 202 is pivoted to or near the frame or a support thereon, as at 201, in such position that the lower end of said catch rests on a projection 212 on the gear 232 and prevents the rotation of said gear save when the catch is swung to one side. Aspring 190 holds this catch in looking position save when the catch is swung aside by outward movement of arm 192, which arm is connected to the catch. This arm 192 is pressed out by the roll or abutment on arm 20 engaging said arm 192 directly after it has operated arm 19 to drop a spalt. Arm 192, being pressed out, swings catch 202 so as to permit the gear 232 to rotate to the extent of one revolution. The starting of the gear draws down abutment or .stop 262 and swings the arm 272 so as to carry the pusher 120 inward toward the saw-carriage, forcing a shingle-bolt 122 before it. The bolt drops onto the supporting parts in position to be grasped by the dogs. A belt 125 leads from a pulley 123 on the shaft of gear 232 to the driving-pulley 125 of an endless conveyer. Shingle-bolts 122 are brought forward by the flights 128 of this conveyer to replace the one taken from the table 282. The bars or flights 128 serve to separate the bolts and hold them in proper position for feeding and also to force the bolts forwardin position to be caught by the pusher 120. The spring 271 permits the pushing-dog 120 to slide under the advancing shin gle-bolt as said dog moves backward. The lower ends of depending lugs 52, 53, and 54 are in different planes and are acted upon by inclines 55, 103, 104i, 105, 106, 107, 57, 108, and 100, which are also in different planes adapting them to act upon the lugs, as heretofore described.

From the foregoing it will be seen that I provide absolutely automatic or self-operating devices for feeding the bolts into the machine and dropping the spalts from the same when the shingles have been cut away so as to leave onlythe spalt, and at the same time I have provided mechanism by which the spalts or blocks may be readily dropped when the operator sets a proper trip for the purpose.

It will also be seen that the tilt-tables are placed under the control of appropriate trips which operate once and are then restored to normal position. The operator has merely to depress the proper trips or handles and the machine does all the rest. No muscular exertion being required from the operator he is at liberty to watch closely the working of the machine and can set the tilts to keep the shingles as near as possible with the grain of the wood and the spalter to throw out any imperfect block with great convenience, safety, and celerity.

This machine has general features in com mon with my patented machine, for which Patent No. 380,346 was granted April 3, 1888, and has also some features resembling those of my application, Serial No. 308,150, filed April 21, 1889'; but the differences are material, and are intended to be specifically pointed out in the respective claims.

I do not desire to be limited to the precise construction of mechanism pointed out in many of the combinations, as itis quite apparent that equivalents 'may be substituted.

WVithout enumerating specifically all the elements it will be understood that the boltfollower indicates generally the arm extending over the position of the bolt in the carriage and such of its operative'connections as are necessary to restore said arm to position above the bolt after the arm has once followed the bolt down until only the spalt remains. It will also be understood that the term spalter refers generally to such mechanism as is used to drop the spalt or waste from the carriage; that the terms incline, abutment, or bearing refer to those parts which, by the engagement of one with the other, cause a shifting of position of some movable part, and that where it is stated that an incline is placed on the frame for a certain purpose, as to engage an arm or slide on the carriage, it will be known to mechanics that the incline may be on the arm or slide, and the so-called incline may be a mere abutment, bearing-piece, or stop, and that the term lever may apply equally as well to an arm or rock-shaft.

The connection of the spalter with the au tomatic feeder renders the machine practically self-operative, since the follower actuates the automatic spalter and the spalter actuates a train of mechanism to put the feeder in operation and thus to throw a new block into the machine.

The terms feeder or carrier are applied to the mechanism for feeding the bolts to the carriage or dogs. The general features of an endless-chain carrier or elevator are embraced in this feeder, but some special adaptations are made to the uses of a shinglemachine, and the device is so connected as to adapt its movements to the requirements of the saw, feeding in a bolt only when a spalt has been thrown out, be the time-interval greater or less.

It will be understood that changes of construction by the substitution of known mechanical equivalents may be made without departing from the spirit of my invention.

In my application, Serial No. 308,150, filed April 21, 1889, I claim, broadly, certain combinations of the movable arm or actuator in its relation to the carriage. The constructions in said application are in some respects like those of the presentapplication, and in other respects they are different. A careful consideration of the claims in said application, which it is hoped may be patented of even date herewith, is invited.

What I claim is 1.
